METHOD FOR SENDING AND TAKING OFF A SIGNAL WITH DIGITAL DATA IN THE POWER DISTRIBUTION NETWORK OF A BUILDING

The invention relates to methods of transmitting digital data (e.g. Internet data, video, audio, voice and/or other data) via power supply systems by means of PLT (Power Line Telecommunication) technology. Its use makes it possible to obtain a technical result in the form of an increase in reliability and speed of transmission of digital data, as well as an increase in the degree of coverage of the rooms in a building (e.g. the flats in a block of flats) with a PLT signal with sufficient power for transmission of digital data. This result is achieved because injection of the digital signal into the electrical mains of the building is effected on a busbar forming part of the power-distributing system of the building. Moreover, the digital signal is injected at least at two points of the busbar. The distances between the points of injection of the digital signal can be established so as to ensure the necessary power of the signal with digital data throughout the power-distributing system of the building, formed from said busbar (e.g. the injection points are arranged uniformly along the busbar or using a special formula). 34 dependent claims, 2 drawings.
